nipper Posted September 5, 2007 Share Posted September 5, 2007 Black is running rich, too much fuel. Can be as simple as a tune up, can be a leaking carb.. nipper Link to comment Share on other sites More sharing options...
j2coe Posted September 5, 2007 Author Share Posted September 5, 2007 it's an 88RX so it should be FI unless somebody swapped something shouldnt be carbed. ECU maybe in limp mode dumping fuel though. Link to comment Share on other sites More sharing options...

Black smoke is managable and fixable. Its the heavy blue and white that require major work. nipper Link to comment Share on other sites More sharing options...
